Theswinging movement of these is limited by supports arranged on the fallfront and/or on the rear wall which do not protrude very much and whichcan be adjusted from the interior of the cabinet by turning a singlecomponent.

DESCRIPTION OF THE PRIOR ART In this sort of cabinet, the fall front maybe swung in an arc, while the straight rods and tubes slidetelescopically one in the other. A certain amount of play is thereforenecessary; this is obtained in usual construction of such a cabinet bymaking the rods and tubes for hanging articles to be stored not onlyswingable about their fixtures but also able to execute an up and overmovement.

The adjustability of the supports for the hanging rods and tubes isprovided for the reason that the material of the cabinet, usually wood,changes in shape on loading, and this therefore often makes necessarysubsequent adjustment of the supports for the hanging devices.Additionally, on account of the small lever arm between the pivot pointof the hanging rods and tubes and the actual support, a substantialpressure is exercised on this support by the weight of the drawings orthe like.

In one known construction adjustable shackles are provided on the innerwall of the cabinet as adjustable supports. In another construction, inwhich the hanging devices can make both a swinging movement about theirfixtures and an up and over movement, grub screws are providedaccessible from outside at the support positions of the hanging rods ortubes, which can be fixed in various positions by means of lockingscrews. It is also known to make both the pivotal fixture for thehanging device or parts and the supports limiting their movement as asingle component. In this construction, for adjusting the support pointof the swingable hanging rods or tubes, a screw threaded rack isprovided in each case which is accessible from the interior of thecabinet. However these screw supports which are adjustable and which arearranged inside the cabinet are difficult to reach. In the cabinetdescribed in the introduction above, the adjustable supports have setscrews against the end of which an arm rigidly connected with eachhanging rod or tube can lie.

It is an object of the present invention to provide, in a cabinet of thetype noted above, a simpler means which is easier to install for theadjustment of the supports. For this no construction would be useable inwhich the adjustable support extended into the interior of the cabinet,since space for storing drawings would be lost and damage to thedrawings by that support would be possible. Additionally, the supportshould be adjustable from the interior of the cabinet since because ofcrowding together adjacent cabinets in use, it is very difficult, or insome cases totally impossible, to carry out any adjustment from outside,especially to the rear wall of the cabinet, if the loaded cabinet islocated against a wall.

GENERAL DESCRIPTION OF THE INVENTION According to the invention, thisproblem is solved in that of the adjustable supports at least oneincludes a turnable disc formed with several support positions aroundits periphery, the support positions being arranged at various distancesfrom the turning axis of the disc.

Since the amount of support adjustment needed is often comparativelysmall it may be sufficient to have a comparatively small number ofcutouts each of different depth around the periphery of such a turnabledisc.

If a greater amount of fine adjustment is desired, this inventioncontemplates that the outer edge of the turnable disc be of generallyspiral shape and depressions of the same size or of various depths beprovided around the periphery, each depression constituting a supportposition.

The turnable disc is provided with a central fixing means, for example athreaded bolt or the like, which simultaneously serves as the axis forrotation. Additionally, according to one embodiment of the inventionthere can be provided on the interior wall of the cabinet and on theside of the turnable disc towards that wall, parts engaging with oneanother and securing the turnable support disc against any undesiredturning. The mutually engaging parts can, according to one embodiment ofthe invention be engaging teeth.

If during use the weight of the sheet element put on the hanging deviceshould change, it is only necessary to loosen the bolt of the turningdisc and to turn the disc through one or more depressions to a suitableex-. tent until the desired position of the hanging rods or tubes isagain reached. Thereby it is possible in simple fashion to fix the newstorage position for the hanging device, which must be so arranged thaton the closing movement of the fall front, both tube and rod cometogether again smoothly and engage in one another without difficulty.

According to a further advantageous embodiment of the invention it iscontemplated to arrange in place of one turnable disc two or even moreturnable discs behind one another, wherein the support positions on eachcan be displaced from one another, in order to provide an improved fineadjustment of the vertical position of the hanging device.

Handling the supports is very simple and they are easily accessible fromthe interior of the cabinet. The construction chosen requires littlespace since a comparatively flat disc can be used which in practice doesnot diminish space inside the cabinet for the receipt of drawings andthe like. Furthermore the construction chosen is simple and economicalto manufacture since the turnable discs may be constructed as stampedpieces and require no further machining operation.

Special openings in the walls of the cabinet for the turnable discs arenot necessary.

DESCRIPTION OF THE DRAWINGS By way of example only, two embodiments ofthe invention are illustrated in the accompanying drawings in which:

FIG. 1 shows a front view of a first embodiment,

FIG. 2 shows a front view of an alternative embodiment, and

FIG. 3 shows schematically a section through a cabinet of knownconstruction for the hanging storage of sheet articles,

FIG. 4 shows a partial longitudinal cross-section through the hangingstorage cabinet, illustrating the type of mounting of the hanging meansand the support for the hanging up means.

According to FIG. 3 a cabinet'4 for the hanging and storage of sheetarticles has a fall front 5 which can be fixed in the closed positionand in the open position (shown in dotted lines) by a locking device 6.The cabinet has a hinged lid 7 which may be lifted up on a hinge 8 atthe back of the cabinet. On the fall from 5 and on the rear wall ofcabinet 4 there are affixed hanging rods and tubes denoted 9 and 10respectively; these are fixed by pivotal means 11 and 12 onto the fallfront 5 and onto the rear wall.

In the section of FIG. 3 only one hanging device 9 and 10 is shown; eachdevice comprises a rod with a pointed end 9 and a tube 10. According tothe invention, the support at least for the tube 10, fixed to the rearwall of cabinet 4, consists of a circular disc 13 of hard material (seeFIG. 1), particularly metal, steel or the like which has about itsperiphery a number of cutouts 14, 14a, 14b, which, seen from theperiphery of disc 13, each have a different depth. The disc 13 is fixedto the inner wall of the cabinet by means of a fixture numbered 15 whichfor example can consist of a bush (not shown) with a threaded bolt,wherein the bush outwardly bears the tumable disc. In an alternativeconstruction, the disc 13 may be supported by a ball bearing.

' FIG. 2 shows a modified construction of the tumable disc, here denoted16, in which the individual support positions, denoted 17, 17a arearranged on a spiral denoted 18, so that the distance from the axis ofrotation of the disc continuously changes. The individual cutouts in theform of support positions 17, 17a may have the same depth or may havesuitably varying depth, in order to increase the possibility ofvariation in the position of the hanging rods 9 or tubes 10.

In order to alter the support position of the hanging device 9, 10 it isonly necessary to loosen any locking of disc 13 or 16 and to turn thedisc one or more cutouts further until the desired height adjustment ofthe support, and thereby the relative position of hanging means 9 and 10to one another, is determined.

From the illustration of FIG. 4 can be seen how the hanging means aremounted within a cabinet and how the support is arranged on the innerwall of the cabinet. In the illustrated embodiment there is fixed in thewall of the cabinet a mounting means 19 with an inner flange 19a for thehanging means, said mounting means carrying a horizontal pin 20 on whichthe hanging means 10 is pivotally supported. The opening in the holdingmeans 19 is adapted to be closed a screw cap 21 or the like.

The flange 19a is provided at 22 with a threaded bore into which bolt 15is screwed to releasably and fixedly adjustably carry the tumable disc13 or 16.

It is possible to provide, on the rear side of the turnable disc and onthe inner wall of the cabinet, additional locking means by which anyundesired turning of the disc is hindered. This locking means can, forexample,

com rise mutually engaging teeth on the rear side of the urnable (118Cand on the inner wall of the cabinet.

The teeth on the inner wall of the cabinet may be formed on a specialinner locking plate.
